Many drivers are still unsure if they want to travel in an autonomous vehicle, but a growing number of auto industry leaders and lawmakers are discussing autonomous driver safety. They promote autonomous vehicles as a safer alternative than humans behind the wheel, removing human error that contributes to auto-related incidents.

"As strange as it might seem to an outside observer; they are safer, a driverless car is less likely to have an accident than a drive one," said Warren Truss, Australia's Deputy Prime Minister, in a statement to Fairfax Media. "If something is about to go wrong, they stop dead. Human error is very significant in accidents, it is rare for there not be some human element."

It could be only a matter of time before an autonomous vehicle actually causes an accident, especially in a dynamic environment such as an urban driving environment, but will it still be safer than human drivers? It looks like it'll be up to automakers to convince drivers about self-driving vehicles, which could be on our roads sooner than we expect.
